You have posted the entire code from your web page which is not helpful. You'll have to step through the debugger and narrow down where the problem lies. No one on here has the time to recreate your form and attempt to recreate the problem you're having.

Find the offending code and provide more specific details as to the problem and we may be able to help.

Step through the code in the debugger and see where the problem is. A brief look at the code shows that you are only incrementing your counter "no" when the letter "u" is matched. I'm guessing this is not what you were wanting. Also, consider re-writing this as a CASE statement rather than a bunch of If / ElseIf statements.

JQuery is a framework that is implemented in Javascript, so they share the same syntax. Your subject line is confusing. You have posted JQuery code but then your subject states that JQuery has more advantages. Can you be more accurate. What is it exactly you are trying to achieve?

We're here to help, not do all the work for you. If you can't create web sites in PHP then consider hiring someone who can. And if you can't create web sites in PHP, why do you care that it's in PHP at all?

Please do some ore investigation into the problem yourself first, and when you have a specific question, then post it here along with the offending code. This question cannot be answered in its current state.

I'm not entirely sure you understand the mechanics of JQuery or client-side scripting. Jquery is a javascript client-side library which means it is executed and runs on the client in the browser. Therefore you need to include your script code either on the ASP page or via a URL. You then need to associate your script with an event on your control so it gets fired. I would spend some time looking through examples of how to use client-side scripting and JQuery first to make sure you fully understand it.

There is far too much code here. Please take the time to step through the code in the debugger and try to see where the problem is arising, and identify the area of the code that is causing the problem. This not only helps you, but it helps us too. If you are still getting problems, then feel free to post again with a more specific questions and specific are of the code.

That value is contained in the web.config file. If no value is specified here, then WCF will use the proxy settings from Internet Explorer. If you have a value specified here then try removing it and see if that gets you working.

Whilst no specific to your question, but in my own Android apps I use structured error handling to catch exceptions, so all my exception handling code is in the one place. Then instead of littering your application with numerous debug statements, you have a single exception handling method which processes your exceptions according to your needs.

Take a read through the concept of structured handling and try / catch blocks and see how you get on. At the very least, it should simplify debugging your application.

The binding doesn't need to be named, in fact none of the elements require a name. Did you remove the reference to the name in your endpoint as I suggested? As long as there are no references to the name elsewhere in the config then it will work.

All the skills you have listed are great if you want to continue as a software developer, but there is a massive leap between development and architecture. The former is working at the small scale of code, whilst the latter is at the much larger scale of the enterprise. Being good at one does not necessarily imply being good at the other. Many excellent developers simply cannot make the transition to architecture.

The best book on the subject is by Martin Fowler. In my opinion it's the architect's bible http://martinfowler.com/books/eaa.html

Personally, I think architecture comes with experience. You can read all the books and take all the courses, but in the end, it's down to judgement and experience. I got into architecture slowly, by firstly designing systems with UML, and gradually designing larger and larger systems. I then designed how multiple systems would communicate, taking into account technological and / or platform boundaries. I then got into SOA and have been lucky enough to work on some very large enterprise applications.

Check out WCF, which is the Microsoft technology for implementing SOA applications. I've written an introductory article here on CP that may be useful http://www.codeproject.com/Articles/835515/Design-a-WCF-Service

You use the emulators to test your app on multiple devices, As such there should be no difference between running your code on a physical device as against an emulator. It's probably a good idea to create test web service for testing your app rather than using localhost, It can still be a locally installed web service running from your LAN. This will be a better test than using localhost.

However if you really do want to use localhost then simply reference it by it's machine name e.g. http://mymachine/mywebservice

If you want help finding a job then there are plenty of job-sites, LinkedIn, newspaper ads, industry press etc that can be of service. Networking (on sites such as this) can also be useful. The QA forum section however, is not the right place to post this.

The way that Facebook does this is using a semantic web vocabulary called FOAF (Friend-of-a-Friend). FOAF is the vocabulary used by social networks such as Facebook when finding friends you have in common with other friends. It does this using the attribute "knows". The full FOAF spec can be found here http://xmlns.com/foaf/0.1/

Are you supplying the credentials in your code when invoking the service? Can you post your code here so we can see exactly what you are doing. This will give us a better idea of how to resolve yur problem.

Are you able to delete the file without using your application i.e. from Windows Explorer? Doing this rules out whether it's your application code or another problem. Do you have delete permissions on the folder?

I would suggest contacting the PayPal online help as this ins't really a technical issue but a PayPal issue. When I had to integrate PayPal into a ecommerce website I found the online help and documentation very useful.

What is the process that creates the JSON in the first place? Surely it makes more sense to fix the data at the source than to try to fix it later on in the process. Fix the process that creates the duplicates in the first place.

As you're getting a WebException exception then it looks like your web page is not able to connect to your web service. Can you open the .asmx page and view the WSDL? Maybe restart your web service and try again. If not then look at the InnerException in the debugger to see if there is an underlying error.

The WCF service works as expected when it's invoked directly from Visual Studio? Can you check your client config to ensure that you are connecting to the correct WCF endpoint.

It might be worth creating a self-hosting console app for your WCF service for debugging purposes. This is how I debug my WCF services before I deploy them to IIS. This is to ensure that the WCF service works correctly when run from a client, in addition to the unit tests that run the code directly from the service. Creating a WCF self-hosted console app is easy and should allow you to properly debug your problem.

Have you bought the domain name? Do you know how to create a website with Tomcat and configure the DNS from your web hosting company? If you know how to do all of this, then the process should be fairly straight-forward. As long as the web hosting has all the necessary files it needs to run your web site, you should be good to go once you have uploaded it to the web server.

As an aside, I place all my namespaces at the top of my code so that I don't clutter my code with the full path i.e. System.IO should be included at the top of your code file so that you don't need to keep referring to it repeatedly throughout your code.

Is there a particular reason why you are using LINQ to determine your connection strings? Why not use the built-in class ConfigurationManager instead? Also, your function reads in the entire contents of the config file to only discard most of it with your LINQ statement. This is inefficient, and for larger files could be costly.

In Visual Studio you should have a toolbar that you use for debugging your app. The toolbar contains a dropdown that contains your attached devices / emulators. To the right of this toolbar is your Android logging. Click on this to bring up the log where you should see the error in more detail.

I'm not posting any more suggestions on this topic as I just keep getting down voted. I have tried to help but if other people do not understand my suggestions, then ask for further clarification rather than down vote someone who is taking the time out from their busy schedule to help. Sorry but I'm outta here.
